| titleOfInvention | METHOD OF PREPARING alpha-SULFO FATTY ACID ALKYL ESTER ALKANOLAMINE SALT |
| abstract | The invention provides a method for the preparation of α-sulfo fatty acid alkylester alkanolamine salt comprising: sulfonating a fatty acid alkyl ester to obtain a sulfonated product, reacting an alcohol and a hydrogen peroxide with the sulfonated product to obtain a reactive product, adding an aqueous alkanolamine solution to the resultant reactive product to obtain a neutralized product having a pH of 2 to 6.5; condensing the neutralized product to obtain an aqueous paste containing α-sulfo fatty acid alkylester alkanolamine salt. n According to the present invention, color deterioration can be inhibited at the time of condensation during preparation of alkanolamine salt of α-sulfo fatty acid alkylester. |
